of small, slender spinules on each side of the notch, and a small, 
irregular, isolated group in the middle, sometimes nearly obso- 
lete, or represented by only one or two small spinules, in the 
larger specimens; just below these there is a similar small 
group on the middle of the first visible arm-plate; the second 
a row of very minute spinules along the upper half. The color 
1s variable; the disk is usually prettily marked by a rosette of 
brown or dark gray spots on a paler ground, or the darker tint 
may take a star-shaped form, with five or with ten rays, with 
the radial shields usually pale; or there may be a combination 
of the rosette and star; rarely the disk is nearly uniform pale 
gray, like the upper side of the arms. The larger specimens 
have the disk 10™™ in diameter ; length of the arms, about 45™, 
his species is rather common in this region, in deep water ; 
we have also frequently dredged it farther north, in the Gulf of 
Maine; Bay of Fundy; and off Nova Scotia.
